What to do if hand pump does not work?

he Saturn boats, rafts and kayak should be inflated until quite firm. If you find the hand pump provided is not able to achieve enough pressure, inspect the hose and all connections for leaks. Remove the hose and block the air outlet at the T handle with the palm or your hand while pushing down on the T handle. You should encounter very substantial resistance to pushing down when the air outlet is blocked. If instead the handle goes down easily, open up the pump by unscrewing the green cylinder lid and inspect the black rubber seal to see if it is torn or improperly installed.

On the end of the plunger you will see 3 ridges: A top ridge, a 2nd ridge that is just below the top one, and a bottom ridge. When the black rubber seal is properly installed it is in the valley between the top ridge and the 2nd ridge, and it covers the 2nd ridge. Photo shows proper location and orientation of the black rubber seal.

The seal is bell-shaped so that its upper opening is smaller in diameter than its lower one. If it is upside down, remove it and turn it over. If it is in the wrong location (i.e., if it is below the 2nd ridge instead of above it), move it to the correct place as shown in the photo.

Once the rubber seal is properly situated, re-assemble the pump, taking care not to damage the seal. Use your fingers, and the fingers of a helper if necessary, to stuff the edges of the seal into the cylinder so that it does not get displaced or damaged as you insert it.
